Was out at the range today and was shooting Russian Tulammo 38 spcl 130gr FMJ standard pressure rounds in my Taurus Model 85 all steel revolver. Went through 10 rounds and all shot fine, loaded next cylinder, and "bang" - went to pull the trigger on round #2 and the trigger wouldn't pull back and the cylinder wouldn't turn. Locked up tight. Cylinder wouldn't open either. Let it sit for about 20 minutes and then the chamber opened, 4 of the rounds fell free and the last wouldn't eject even using the ejector rod. Had to use a pen to knock it out. Upon inspection, the case was split to the point of light coming through. I can see no damage to the revolver at all, and now it cycles fine, but this is the last time I use this Russian crap to save a few $$$ in pistols. Sure, I'll keep using it in my AK and SKS, but it seems like this isn't an isolated thing with using it in revolvers; the steel swells and doesn't contract back like brass and I've found lots of other reports of split cases with this Tulammo 38 spcl.
